I got it to boot by doing a:
grub-install '(hd0)'
the /boot/grub/device.map must point grub to the right location for hd0, check that once. Also, grub has not been updated in 5.1 at all, so I would think your problem is not related to the update at all. When was the last time you rebooted the machine :)
device.map contains:
(fd0) /dev/fd0 (hd0) /dev/cciss/c0d0
However, I've noticed that grub-install is not telling the truth:
# grub-install /dev/cciss/c0d0 expr: non-numeric argument Installation finished. No error reported. This is the contents of the device map /boot/grub/device.map. Check if this is correct or not. If any of the lines is incorrect, fix it and re-run the script `grub-install'.
(fd0) /dev/fd0 (hd0) /dev/cciss/c0d0
# grub-install '(hd0)' Installation finished. No error reported. This is the contents of the device map /boot/grub/device.map. Check if this is correct or not. If any of the lines is incorrect, fix it and re-run the script `grub-install'.
(fd0) /dev/fd0 (hd0) /dev/cciss/c0d0
In the first case it says that no errors are reported, however there's a message from expr that something has gone wrong. The stage2 file produced by the two commands differ.
If I add a "set -x" to a copy of the grub-install command and do a diff on the output I get:
... < ++ tmp_drive='(hd0)' < ++ test 'x(hd0)' = x < ++ test x/dev/cciss/c0d0 '!=' x < ++ case "$host_os" in < ++ echo '(hd0)' < +++ expr /dev/cciss/c0d0 - 1 < expr: non-numeric argument ... 508c451
< + install_boot_block '(hd0,0)' '(hd0,)'
- install_boot_block '(hd0,0)' '(hd0)'
...
The machine reboots automatically during the weekend if a new kernel has been installed, yum update runs daily, so it has been rebooted.

I have never gotten grub to install to a linux device name. It always wants a defined drive in the device.map. I always thought I was doing something wrong, and resolved myself to always check the device.map first.
